Embedded Digital Watermarks for Image Control on Web

Years ago I used a service called Digimarc that provided me with a code to embed into my images using a Photoshop plugin. When my image was released onto the web Digimarc would scour the net to find if my image(s) were being used elsewhere. The image could automatically provide a viewer my contact info in case someone wanted to purchase rights or ask for something. This is a very useful service but had some flaws, then became too costly for me to maintain, then it seemed the company changed and dropped the service altogether but seem to be back in business. Would ASF members care to nudge ASF into providing us with this type of service that is included with our yearly service fee? I feel my work is exposed and could be used by others without my knowledge, consent, or compensation.
